thanks for coming to us on this friday. millions of people see movies each and every month and in these rare situations, where we're unfortunately talking about a catastrophe at a public venue, what can people do if they are in this situation? >> one of the first things that you can do is to pay attention to the primer at the beginning of the film, they tell you where the exits are. oftentimes, people tend to ignore that. >> and to theatres? >> and the theatres can also prep their people in the theatres so they know that if the certain type of an emergency breaks out, that they have protocalls of operation for the people to respond in certain ways to specific types of emergencies. >> so, are theatre owners now in a position where they have to think about attacks like this and having to predict? >> i think they have to have a set of rules in place so they know they're going to respond in a certain way to a certain type of crisis. i don't think they have to plan for this. i would hope this wouldn't happen frequently enough wh
